Hi Team, We are trying to upgrade our on premise instance from the below version. 3.2.0.beta5-dev to 3.5.0.beta7 And we are seeing the below error. /var/discourse# ./launcher rebuild app ERROR: Docker version 18.06.1-ce not supported, please upgrade to at least 20.10.0, or recommended 24.0.7 Please help in getting this sorted out as we need to upgrade our instance on priority to address few vulnerabilities found in the current version. [image]

Another user had a similar issue: [image]My discourse forum crashed after upgrade to 3.5.0.beta8 You can try the following cd /var/discourse git pull origin main --autostash

We are seeing the below error git pull origin main --autostash error: unknown option `autostash’ usage: git fetch [] [ […]] or: git fetch [] or: git fetch --multiple [] [( | )…] or: git fetch --all [] Our version git --version git version 1.9.1

Your OS is almost certainly out of date too. The easiest thing is to create a new VM with a new OS and a new Docker, install Discourse and restore a backup. It’s possible that you can upgrade docker and try again, but you’ll still need to deal with the PostgreSQL 15 update. Moving to a new server will require little downtime and zero chance of leaving your system in a broken state.

I think you need to update your Git version.
